+2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
+
+ Update to latest gnulib and gettext versions.
+ * bootstrap (gnulib-modules): Remove hard-locale, stdio-safer.
+ Add fopen-safer.
+ (gnulib_files): Add m4/warning.m4. Don't worry about files
+ overwritten by autopoint.
+ Replace gt_INTL_SUBDIR_CORE with an empty body in m4/gettext_gl.m4.
+ Suppress "id", "ms", "tr" translations for now, since gettext 0.15
+ rejects them.
+ Don't use autoreconf; instead, invoke autopoint etc. by hand,
+ so that we can remove the intl files at a better time.
+ (intl_files_to_remove): Remove aclocal.m4, since it gets
+ rebuilt anyway. Remove m4/inttypes_h.m4, m4/inttypes.m4,
+ m4/isc-posix.m4, m4/lib-ld.m4, m4/lib-prefix.m4, m4/po.m4,
+ m4/stdint_h.m4, m4/uintmax_t.m4, m4/ulonglong.m4.
+ Add m4/inttypes-h.m4, m4/lock.m4, m4/visibility.m4.
+ Remove datarootdir hack; no longer needed.
+ * configure.ac: Use gl_WARNING_CFLAGS rather than BISON_WARNING.
+ (AM_GNU_GETTEXT_VERSION): Bump from 0.12 to 0.15.
+ * lib/.cvsignore: Remove hard-locale.c, hard-locale.h, strdup.c,
+ strdup.h.
+ * m4/.cvsignore: Remove hard-locale.m4, strdup.m4.
+ * m4/warning.m4: Remove from CVS, since we now use gnulib's version.
+
+2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
+
+ * bootstrap: Adjust to today's change to gnulib-tool by invoking
+ it with --assume-autoconf='latest-stable'.
+
+2006-07-13 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/parse-gram.y (grammar_declaration): Don't confuse Doxygen (at
+ least 1.4.7 and 1.4.4) by putting a #line between `typedef union
+ YYSTYPE' and `{'.
+ * src/muscle_tab.h (muscle_grow): Replace the header comments with
+ those from muscle_tab.c since the old ones are misleading.
+
+2006-07-13 Akim Demaille <akim@epita.fr>
+
+ Support %define "KEY" {VALUE}.
+ * src/scan-code.h, src/scan-code.l (translate_action)
+ (translate_rule_action, translate_symbol_action, translate_code):
+ Return char *, not const char *.
+ * src/parse-gram.y (declaration): Rename as...
+ (prologue_declaration): this.
+ (string_content): Remove this nonterminal, use STRING.
+ (braceless, content, content.opt): New nonterminal.
+ Use them.
+ (%define): Now accept content.opt, i.e., accept also BRACED_CODE
+ as value.
+ * src/scan-gram.l (getargs.h): Don't include it.
+
+2006-07-12 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/lalr1.cc (YYCDEBUG): Use 'if (yydebug_) (*yycdebug_)'
+ rather than a for-loop that declares a local bool variable. This
+ should work around a compatibility problem with a Cray x1e C++
+ compiler reported by Hung Nguyen in
+ <http://lists.gnu.org/archive/html/help-bison/2006-07/msg00022.html>.
+ The for-loop was introduced in the 2004-11-17 change but I don't
+ know why it was needed.
+
+2006-07-12 Akim Demaille <akim@epita.fr>
+
+ * data/c.m4: Comment changes.
+
+2006-07-10 Akim Demaille <akim@lrde.epita.fr>
+
+ * src/complain.c (error_message, ERROR_MESSAGE): New.
+ To factor...
+ (fatal_at, fatal, warn_at, warn, complain_at, complain): these.
+ * src/complain.h, src/complain.c (warning_issued): Remove, unused.
+
+2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * NEWS: Instead of %union, you can define and use your own union type
+ YYSTYPE if your grammar contains at least one <type> tag.
+ Your YYSTYPE need not be a macro; it can be a typedef.
+ * doc/bison.texinfo (Value Type, Multiple Types, Location Type):
+ (Union Decl, Decl Summary): Document this.
+ * data/glr.c (YYSTYPE): Implement this.
+ * data/glr.cc (YYSTYPE): Likewise.
+ * data/lalr1.cc (YYSTYPE): Likewise.
+ * data/yacc.c (YYSTYPE): Likewise.
+ * src/output.c (prepare): Output tag_seen_flag.
+ * src/parse-gram.y (declaration, grammar_declaration):
+ Use 'union_seen' rather than 'typed' to determine whether
+ %union has been seen, since grammars can now be typed without
+ %union.
+ (symbol_declaration, type.opt, symbol_def):
+ Keep track of whether a tag has been seen.
+ * src/reader.c (union_seen, tag_seen): New vars.
+ (typed): remove.
+ * src/reader.h (union_seen, tag_seen, typed): Likewise.
+ * src/scan-code.l (untyped_var_seen): New variable.
+ (handle_action_dollar): Adjust to above changes.
+ (handle_action_dollar, handle_action_at):
+ Improve overflow checking for outlandish numbers.
+ * tests/input.at (AT_CHECK_UNUSED_VALUES): Redo test to
+ avoid new diagnostics generated by above changes.
+ * tests/regression.at (YYSTYPE typedef): Add test to check
+ for type tags without %union.
+
+ * src/symlist.c (symbol_list_length): Return int, not unsigned
+ int, since callers expect int. This may need to get revisited
+ once we have proper integer overflow checking.
+
+ * src/scan-gram.h (gram_scanner_cursor): Remove decl, since this
+ object is now static.
+
+ * src/getargs.c (flags_argmatch): Return void, not int,
+ to pacify ./configure --enable-gcc-warnings.
+
+ * src/flex-scanner.h (STRING_FREE): Don't use FLEX_PREFIX (last_string)
+ since last_string is already defined to FLEX_PREFIX (last_string).
+
+2006-07-09 Akim Demaille <akim@lrde.epita.fr>
+
+ Implement --warnings/-W.
+ * src/getargs.c (report_argmatch, trace_argmatch): Remove,
+ replaced by...
+ (flags_argmatch, FLAGS_ARGMATCH): this new function and macro.
+ Adjust callers.
+ * src/getargs.h, src/getargs.c (warnings, warnings_flags)
+ (warnings_args, warnings_types): New.
+ (getargs, short_options, long_options): Accept -W/--warnings.
+ Sort the options by alphabetical order, upper case letter right
+ before its lower case.
+
+2006-07-09 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Change %merge result type clash warnings to errors. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-07/msg00026.html>.
+ * src/reader.c (record_merge_function_type): Use complain_at.
+ * tests/glr-regression.at (Missed %merge type warnings when LHS type is
+ declared later): Update test case results.
+
+2006-07-09 Akim Demaille <akim@lrde.epita.fr>
+
+ * src/getargs.h, src/getargs.c: Swap --report and --trace handling
+ to be in alphabetical order.
+ (trace_args): Spelling fixes.
+
+2006-07-09 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/yacc.c (YYID, yy_stack_print): Prefix local vars with "yy"
+ so they don't collide with user-defined macros.
+ (yy_stack_print): Don't assume that yytype_int16 promotes to int;
+ this was never guaranteed, and now that we're using gnulib stdint,
+ which defines int_fast16_t to long int, the problem is exposed.
+
+2006-07-08 Paul Eggert <eggert@cs.ucla.edu>
+
+ * data/c.m4 (b4_basename): Simplify a bit, since we don't
+ need the full POSIX semantics (and weren't implementing them
+ anyway).
+
+ Adjust to Autoconf 2.60 and today's gnulib.
+ * bootstrap (gnulib_modules): Add stdint.
+ Remove special case for m4/onceonly_2_57.m4, since gnulib-tool
+ no longer copies it.
+ (intl_files_to_remove): Remove m4/longlong.m4 and m4/wchar_t.m4,
+ since stdint needs the former and wcwidth (which is now required
+ by mbswidth) needs the latter.
+ Append 'datarootdir = @datarootdir@' to po/Makefile.in.in, to
+ work around a compatibility glitch between gettext 0.14.6 and
+ Autoconf 2.60.
+ * configure.ac (AC_PREREQ): Require Autoconf 2.60.
+ Do not check for uintptr_t, since new stdint module does the right
+ thing.
+ * lib/.cvsignore: Remove alloca.c, alloca.h, alloca_.h.
+ Add stdint.h, stdint_.h, wcwidth.h.
+ * m4/.cvsignore: Remove alloca.m4, onceonly.m4.
+ Add absolute-header.m4, double-slash-root.m4, longlong.m4,
+ stdint.m4, wchar_t.m4, wcwidth.m4.
+ * src/files.c: Include <dirname.h> and <stdio-safer.h> in the
+ usual order for ../lib/*.h files.
+ (file_name_split): Use last_component, not base_name, to adjust
+ to gnulib changes.
+ * src/parse-gram.h: Include <strverscmp.h> in the usual order
+ for ../lib/*.h files.
+ (YYTYPE_INT16, YYTYPE_INT8, YYTYPE_UINT16, YYTYPE_UINT8):
+ Define unconditionally, since we now assume the stdint module.
+ * src/scan-skel.l: Include <dirname.h>.
+ (BASE_QPUTS): Use last_component, not base_name.
+ * src/system.h: Include <unlocked-io.h> in the usual order
+ for ../lib/*.h files. Include <stdint.h> unconditionally,
+ since we now use the stdint module.
+ (uintptr_t): Declare if UINTPTR_MAX is not defined, not
+ HAVE_UINTPTR_T, since we now use the stdint module.
+ (base_name): Remove decl, since files now include <dirname.h>
+ to get the decl.
+
+2006-07-08 Akim Demaille <akim@lrde.epita.fr>
+
+ * data/c.m4 (b4_location_initial_column, b4_location_initial_line):
+ New, default to 1.
+ * data/yacc.c, data/glr.c, data/location.cc: Use them.
+ * NEWS, doc/bison.texinfo: The initial column and line are 1 by
+ default.
+ * tests/calc.at: Adjust.
+
+2006-07-08 Akim Demaille <akim@lrde.epita.fr>
+
+ * data/c.m4 (b4_basename): New.
+ (b4_syncline): Also output the location of its invocation (from
+ the skeleton).
+ (b4_user_action, b4_define_user_action, b4_user_actions)
+ (b4_user_initial_action, b4_user_post_prologue, b4_user_start_header)
+ (b4_user_stype): New.
+ * data/yacc.c, data/glr.c, data/lalr1.cc, data/glr.cc: Use them.
+
+2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ In the grammar file, the first column is 1 not 0 on the first line as
+ on every other line.
+ * src/parse-gram.y (%initial-action): Initialize @$ correctly.
+ * tests/input.at (Torturing the Scanner): Update output.
+
+ * src/scan-gram.l (scanner_cursor): Declare it static.
+
+2006-07-07 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ In warnings, say "previous declaration" rather than "first
+ declaration".
+ * src/symtab.c (redeclaration): Do that here.
+ * src/reader.c (record_merge_function_type): In the case of a result
+ type clash, report the previous declaration rather than the very first
+ one in the grammar file.
+ * tests/glr-regression.at (Missed %merge type warnings when LHS type is
+ declared later): Add a third declaration to check this behavior.
+ * tests/input.at (Incompatible Aliases): Update output.
+
+2006-06-27 Akim Demaille <akim@epita.fr>
+
+ * doc/Doxyfile.in: New.
+ * doc/Makefile.am: Use it.
+ * src/lalr.h, src/symtab.h: Initial doxygenation.
+
+2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't miss %merge result type warnings just because the LHS types are
+ declared after the %merge. This continues the effort of the previous
+ patch.
+ * src/reader.c (get_merge_function): Don't set the merger type yet.
+ (record_merge_function_type): New function for setting the merger type
+ and checking for clashes.
+ (grammar_current_rule_merge_set): Set the location of the %merge for
+ the current rule.
+ (packgram): Invoke record_merge_function_type for each rule now that
+ all symbol type declarations have been parsed.
+ * src/reader.h (merger_list.type_declaration_location): New member
+ storing the location of the first %merge from which the type for this
+ merging function was derived.
+ * src/symlist.h (symbol_list.merger_declaration_location): New member
+ storing the location of a rule's %merge, if any.
+ * tests/glr-regression.at (Missed %merge type warnings when LHS type is
+ declared later): New test to catch the error fixed by the above patch.
+
+2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Get action warnings (grammar_rule_check) right even when symbol
+ declarations appear after the rules. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00108.html>
+ and
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00151.html>.
+ Don't mistake the type of $$ in a midrule to be that of its parent
+ rule's $$.
+ * src/reader.c (grammar_current_rule_end): Don't invoke
+ grammar_rule_check yet since not all symbol declarations may have been
+ parsed yet.
+ (grammar_midrule_action): Likewise.
+ Don't record whether the midrule's $$ has been used yet since actions
+ haven't been translated yet.
+ Record the midrule's parent rule and its RHS index within the parent
+ rule.
+ (grammar_current_rule_action_append): Don't translate the action yet
+ since not all symbol declarations may have been parsed yet and, thus,
+ warnings about types for $$, $n, @$, and @n can't be reported yet.
+ (packgram): Translate the action and invoke grammar_rule_check now that
+ all symbol declarations have been parsed.
+ * src/scan-code.l (handle_action_dollar): Now that this is invoked
+ after parsing the entire grammar file, the symbol list here in the case
+ of a midrule is actually the midrule's empty RHS, so reference its
+ parent rule's RHS where necessary.
+ On the other hand, now that you can already know it's a midrule, you
+ aren't forced to think $$ has the same type as its parent rule's $$.
+ (handle_action_at): In the case of a midrule, reference the parent rule
+ where necessary.
+ * src/symlist.c (symbol_list_new): Initialize new midrule-related
+ members.
+ (symbol_list_length): Now that this is invoked after all rules have
+ been parsed, a NULL symbol (rather than a NULL symbol list node)
+ terminates a rule. symbol_list_print already does this correctly.
+ * src/symlist.h (symbol_list.midrule_parent_rule,
+ symbol_list.midrule_parent_rhs_index): New members so that midrules can
+ remember their relationships with their parents.
+ * tests/input.at (Type Clashes): Extend to catch the midrule $$ error
+ fixed by the above patch.
+ (_AT_UNUSED_VALUES_DECLARATIONS, AT_CHECK_UNUSED_VALUES): New m4 macros
+ implementing...
+ (Unused values): ... this old test case and...
+ (Unused values before symbol declarations): ... this new test case.
+ This one is the same as `Unused values' except that all symbol
+ declarations appear after the rules in order to catch the rest of the
+ errors fixed by the above patch.
+
+2006-06-26 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ More cleanup.
+ * src/reader.c (current_rule): Declare it static since it's no longer
+ used outside this file.
+ (grammar_current_rule_action_append): Remove redundant arguments from
+ translate_rule_action invocation.
+ * src/reader.h (current_rule): Remove this unused extern.
+ * src/scan-code.h (translate_rule_action): Remove redundant arguments.
+ * src/scan-code.l (translate_rule_action): Likewise.
+
+2006-06-25 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Clean up yesterday's patch.
+ * parse-gram.y (rhs): Move grammar_midrule_action invocation from here
+ to...
+ * src/reader.c (grammar_current_rule_action_append): ... here for
+ consistency with grammar_current_rule_symbol_append.
+ * tests/regression.at (Braced code in declaration in rules section):
+ Make yyerror and yylex static as usual.
+
+2006-06-24 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Fix bug that mistakes braced code in a declaration in the rules section
+ to be a rule action. Mentioned at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00105.html>.
+ * src/scan-gram.l: Move midrule action detection from the start of the
+ scanning of any braced code to...
+ * src/parse-gram.y (rhs): ... the parsing of braced code as a rule
+ action. For readability, use $2 and @2 rather than the equivalent
+ global variables.
+ * tests/regression.at (Braced code in declaration in rules section):
+ New test to catch the error fixed by the above patch.
+
+ Work on code readability some.
+ * src/scan-code.l (current_rule): Get rid of this misleading and
+ redundant declaration: it's actually extern'ed in reader.h.
+ (YY_DECL, code_lex, handle_action_dollar, handle_action_at,
+ translate_action): Add a rule argument and use it instead of the global
+ current_rule.
+ (translate_rule_action): This already receives current_rule through an
+ argument, so pass it on to translate_action instead of assigning
+ current_rule to current_rule.
+ (translate_symbol_action, translate_code): Pass rule = NULL to
+ translate_action.
+
+2006-06-23 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Rename %before-definitions to %start-header and %after-definitions to
+ %end-header. Don't use these declarations to separate pre-prologue
+ blocks from post-prologue blocks. Add new order-independent
+ declarations %before-header and %after-header as alternatives to the
+ traditional Yacc pre-prologue and post-prologue blocks. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00110.html>.
+ * NEWS (2.3+): Update for these changes.
+ * data/glr.c (b4_before_definitions): Update to...

+ (Calc++ Parser): Likewise.
+ (Bison Declaration Summary): Update names.
+ (Bison Symbols): Update description.
+ * src/parse-gram.y (PERCENT_AFTER_DEFINITIONS): Update to...

+ (PERCENT_BEFORE_DEFINITIONS): Update to...
+ (PERCENT_START_HEADER): ... this.
+ (PERCENT_AFTER_HEADER, PERCENT_BEFORE_HEADER): New tokens.
+ (declaration): Update token names and m4 macro names.
+ When parsing %end-header and %start-header, invoke translate_code
+ before muscle_code_grow, and no longer set global booleans to remember
+ whether these declarations have been seen.
+ Parse new %after-header and %before-header.
+ * src/reader.c (before_definitions, after_definitions): Remove.
+ (prologue_augment): Accept a new bool argument to specify whether to

+ * tests/actions.at (Printers and Destructors): Update names.
+
+2006-06-22 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Add comparison operators for C++ location classes. Discussed at
+ <http://lists.gnu.org/archive/html/bison-patches/2006-06/msg00092.html>.
+ * data/c++.m4 (b4_define_location_comparison): New boolean %define
+ declaration indicating whether filename_type has an operator==. If
+ filename_type is `std::string', it defaults to `1', `0' otherwise.
+ * data/location.cc: Iff b4_define_location_comparison is `1', add
+ operator== and operator!= for class position and for class location.
+
+ Some minor fixes.
+ * src/scan-action.l: Remove unused file.
+ * src/symtab.c (symbol_printer_set): Use printer_location not
+ destructor_location.
+ * src/symtab.h (struct symbol): Replace incorrect source comment for
+ printer members.
+ * tests/input.at (Incompatible Aliases): Update output with correct
+ printer location.
+
+2006-06-20 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ Don't put the pre-prologue in the header file. For the yacc.c code
+ file and the glr.c header and code files, move the pre-prologue before
+ the token definitions. Add new %before-definitions and

+ * NEWS (2.3+): Describe these changes.
+ * data/glr.c (b4_pre_prologue): Move from within to before...

+ Add new b4_before_definitions before b4_token_enums.
+ Add new b4_after_definitions at the end.
+ * data/glr.cc (b4_pre_prologue): Replace with...

+ (b4_after_definitions): New near the end of the header file.
+ * data/yacc.c: Clean up some m4 quoting especially in the header file.
+ (b4_token_enums_defines): In the code file, move to right before
+ YYSTYPE for consistency with the header file.
+ (b4_before_definitions): New right before b4_token_enums_defines in
+ both the header and code file.
+ (b4_after_definitions): New right after YYLTYPE and yylloc in both the
+ header and code file.
+ * doc/bison.texinfo (Prologue): Show use of %before-definitions instead
+ of prologues for %union dependencies.
+ (Bison Declaration Summary): In %defines description, mention the
+ effect of %before-definitions and %after-definitions on the header
+ file.
+ (Calc++ Parser): Forward declare driver in a %before-definitions rather
+ than in the pre-prologue so that make check succeeds.
+ (Bison Symbols): Add entries for %before-definitions and
+ %after-definitions.
+ * src/parse-gram.y (PERCENT_BEFORE_DEFINITIONS): New token for
+ %before-definitions.
+ (PERCENT_AFTER_DEFINITIONS): New token for %after-definitions.
+ (declaration): Parse those declarations and append to

+ * src/reader.c (before_definitions, after_definitions): New bools to
+ track whether those declarations have been seen.
+ (prologue_augment): Add to the post-prologue if %union,
+ %before-definitions, or %after-definitions has been seen.
+ * src/reader.h (before_definitions, after_definitions): New extern's.
+ * src/scan-gram.l: Scan the new declarations.
+ * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Place the second
+ prologue block in a %before-definitions or a %after-definitions based
+ on whether the %union is declared.
+ * tests/regression.at (Early token definitions with --yacc, Early token
+ definitions without --yacc): Move tests for token definitions into the
+ post-prologue since token names are no longer defined in the
+ pre-prologue.
+
+2006-06-20 Akim Demaille <akim@epita.fr>
+

+ * src/parse-gram.y: Use it.
+
+2006-06-19 Joel E. Denny <jdenny@ces.clemson.edu>
+
+ * src/scan-gram.l: Remove unused declaration of last_string_1 so the

+
+2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
+
+ * src/parse-gram.y (char_name): New function.
+ (CHAR, STRING, string_content): For %printer, properly escape.
+ (ID): Prefer fputs to fprintf.
+ (id): Reindent to be consistent with other rules.
+ Properly quote char.
+
+ The Translation Project changed its way of publishing translations
+ to maintainers. I haven't received any responses to my request
+ for supporting the old way, or for documenting the new way. I
+ have modified 'bootstrap' to use screen scraping
+ (in this case, HTML scraping). This is unreliable and inelegant,
+ but I don't see any better way. Yuck.
+ * bootstrap (TP_URL, WGET_COMMAND): New vars.
+ (get_translations): New function, which uses HTML scraping to
+ deduce locations of latest translations.
+ Use this function to grab both bison and bison-runtime .po files.
+ Don't bother priming the pump for the runtime-po domain any more,
+ as it's now translated better than bison is.

+ * src/scan-gram.l: No longer "parse" things after `%union' until
+ `{'. Rather, return a single "%union" token.
+ No longer make symbols: return strings, and leave the conversion
+ to symbols to the parser.
+ (SC_PRE_CODE, token_type): Remove.
+ * src/parse-gram.y (%union): New field `character'.
+ Sort tokens.
+ (CHAR): New token.
+ (ID, ID_COLON): Now that the scanner no longer makes them
+ identifiers, adjust all uses to invoke symbol_get.
+ (id_colon): New, wraps the conversion from string to symbol.
+ (%union): Accept a possible union_name.
+ (symbol): Now can be a char.
+ * data/c.m4 (b4_union_name): Leave a default value.
+ * data/glr.c, data/yacc.c: Use it.
